compose2 Posted January 4, 2005 Report Posted January 4, 2005 my previous post stated that my shee would cold start only if i used starter fluid. i checked everything and its still the same prob. i recently trying pulling the choke out 1/2 when it was idling and warm, but it stalled right away. i thought that the rpm's show rise. gimme some feed back, tell me what you think it could be Quote
compose2 Posted January 4, 2005 Author Report Posted January 4, 2005 Try a larger pilot?? 301610[/snapback] i know i still have the stock pilots, but it maintains great idle and doesn't bog or anything when i rap on the throttle. i had dealership tell me that seldom do you need to change the pilot jet. how can i inspect the choke? is there anything i can see that would tell me its bad?

Banchetta Posted January 4, 2005 Report Posted January 4, 2005 make sure the choke carb has the right bowl on it..If you swap the bowls, then it wont work...the choke carb bowl has a brass tube w/ a tiny jet on the bottom of the bowl. Also make sure the carb slide aren't in backwards, (cutaway should face the air box), then check to make sure your compression is up there. Low compression will create starting problems..Also make sure the choke tube is in place. Quote
compose2 Posted January 4, 2005 Author Report Posted January 4, 2005 been through all that. i tried switching the float bowl, made it worse. i made sure the crossover tube is connected. i just rebuilt the motor. 140lbs per cylinder. im clueless unless my choke is bad. is that possible? the motor should rev when i pull the choke but it bogs and stalls instead Quote

Have you tried shaking the shee before starting? I switched oils on mine and it starts hard and runs shitty for a couple of minutes unless I shake it around, even then its still not perfect. The oil and gas can separate, I see it, so I can believe it. If not that, then I'd try a larger pilot, you might have to lower the needles one clip, but try it first. Quote
compose2 Posted January 4, 2005 Author Report Posted January 4, 2005 i run all yamalube fluids in my shee. i tried shaking it and it made no difference. the strange thing is that it runs great once it started. plus if i shut it down while its warm, it will start on one kick Quote
Banchetta Posted January 4, 2005 Report Posted January 4, 2005 Have you tried a leakdown test?? You might have enough of a leak to suck air and not enough fuel..... Quote

Banchetta Posted January 4, 2005 Report Posted January 4, 2005 Duncanracing.com has a diagram on how to make one. Cost you about $30 and you'll have it forever..you'll be able to find leaks in the intakes as well as the crankcase seals.. Quote
