Snopczynski Posted March 18, 2009 Report Share Posted March 18, 2009 Are the slides in backwards, is the choke balance tube on, are the bowls on the correct carburetor? Quote Link to comment Share on other sites More sharing options...
lokisbuddy Posted March 19, 2009 Author Report Share Posted March 19, 2009 I have the bowls on the correct carb, though they are exactly the same. The rubber was from a piece of fuel tubing as far as I can tell, needle valves look good, I did not mix oil and my choke tube is on. I was thinking needles but I had them in before and it ran great. Overboost, where are you located? Anywhere by burton? I might take you up on that offer just to see if it cures the problem. (If it does I will just buy new carbs) The only changes I have made since it ran good were the floats. Quote Link to comment Share on other sites More sharing options...
tidos76 Posted March 19, 2009 Report Share Posted March 19, 2009 (edited) Have you checked your plugs? Only time i've ever lost low end like that i had fouled plugs. Edited March 19, 2009 by tidos76 Quote Link to comment Share on other sites More sharing options...
lambchop Posted March 19, 2009 Report Share Posted March 19, 2009 Had a problem similar to this myself. Believe it or not traced it down to a stopped up petcok. Try bypassing the petcock that's how I traced it. The flow from the tank seemed very slow to me, almost to a drip when it was wide open. Cleaned it out real good and voila!!!

Rodneya Posted March 19, 2009 Report Share Posted March 19, 2009 I have the bowls on the correct carb, though they are exactly the same. The choke side bowl is different from the other, it has a jet in it for the choke. There is no such thing as a float adjustment tool, and don't waste your time with a socket. Just use a ruler or tape measure. You are asking for help again, but you have not used the advice given before. I know you mentioned you were out of work at the moment, but you gotta get new needles and the floats set correctly before you try get the carbs set. and those minature air filters you have may be too restrictive for the pipes. Just a thought. Patience, and good luck Quote Link to comment Share on other sites More sharing options...
lokisbuddy Posted March 19, 2009 Author Report Share Posted March 19, 2009 (edited) Dude I always follow peoples advice, in fact yesterday after everyone was poting me advice I was going out and checking it after I already checked it to begin with. The only thing I did not check yet was the petcock. I am having a buddies dads friend look at it, I guess he is an engine wizard and builds a arms and swing arms and races so maybe he can help. Edit: Oh and my fuel bowls are exactly the same, so maybe they were taken off different carbs or something. Would that cause a problem? (shouldnt it ran good before) Edited March 19, 2009 by lokisbuddy Quote Link to comment Share on other sites More sharing options...

lokisbuddy Posted March 19, 2009 Author Report Share Posted March 19, 2009 You never answered on wether the carb slides are in backwards or not. Does it have spark? Does it have good compression? Oh sorry yeah I learned my lesson about putting the slides in backwards about 2 weeks ago lol. The slides are correct, Has good spark runs great when I first start it, when Its time to pull it off choke I do and when I give it gas it bogs out and dies. I don't have a compression gauge right now (I traded it for a chevy 350 along with a set of sk tools ) But the compression feels the same as it did before when I first got her. Does it sound like it could be blown up? Quote Link to comment Share on other sites More sharing options...
jjn56 Posted March 19, 2009 Report Share Posted March 19, 2009 Have you tried new plugs yet or re-gapping them. I had a similar prob this weekend and all I did to fix it was open up the gap on the plugs (after trying 75 other things that didn't work) Quote Link to comment Share on other sites More sharing options...
lokisbuddy Posted March 19, 2009 Author Report Share Posted March 19, 2009 I haven't tried new plugs yet, think that would cause it to run good on choke but not off choke? I will try those when I get some new plugs. I am broke right now though, maybe I will put my plugs in the cleaner then try them. Also I pulled my carbs off and cleaned the airjets in both fuel bowls and felt for air coming out of the reed cages. The air coming from the right cage is very minimal but I can feel it puff out of the left when I kick it over. I can't understand this because I pulled them and looked at them and they lookd fine no gaps or cracks. I think I may have installed them upside down though, do the two lines on the outer reed cage go under or on top? Thanks for the help guys I really appreciate it.

Overboost Posted March 19, 2009 Report Share Posted March 19, 2009 I am acually in grand blanc by the mundy/GB/burton border. I can walk to burton in 5 min, not that I would want to walk there, I moved out for a reason. Quote Link to comment Share on other sites More sharing options...
lokisbuddy Posted March 19, 2009 Author Report Share Posted March 19, 2009 (edited) Haha you dont like burton? I like burton alot better than flint. I lived in flint for a year on the east side. We used to drink at this bar in burton called jester something. I go to burton like once a month. Oh and a bar called the red baron or something like that?

lokisbuddy Posted March 19, 2009 Author Report Share Posted March 19, 2009 Ok guys I cleaned my plugs off and checked the gap, fired it up and the thing ran awesome, started bogging a bit so I took it off choke and went to blip the throttle and it fell on its face and died. I pulled the plugs and there is oil on them. What would cause oil to build up on the plugs that fast? I checked the pilots again and they are clean. (stock pilots) Needle is on the third notch.

Snopczynski Posted March 19, 2009 Report Share Posted March 19, 2009 A misplaced jet, bad reeds, improperly set float height, torn choke crossover tube can cause issues like this. Did it ever run good with this setup you have now? Quote Link to comment Share on other sites More sharing options...
