39 keihins all the way. If you look on ebay you can come accross pumpers for around $120.

I would go with the 41 pwks

I wouldn't go with a pump to run 300 ft with a 10 mil Cub. You barely need billet bowls (may not need them at all, but I wouldn't chance it on a 10 mil). A pump is just one more headache to deal with. You can run the 39 PWKs, 41 Lectrons, 38 TM Mikunis. All would be good choices. Just choose the one that your more familiar tuning. I love the Lectrons on my 10 mil Cub, but I run 38 and 39 PWKS on my other Cubs.

Everyones entitled to their opinions. Ive ran lectrons and keihins, both on 10mills. You can find 41's for around the same price. Lectrons are nice, but for the price, i dont think its worth it. I ran just as fast with my $150 keihins, lol

I prefer a pumper carb not for fuel requirements but for convenience and assurance. To me they are not something else to worry about IMO.....they save me from worrying.

 

W/a pumper you def. don't have to worry about fuel requirements, i don't have to remember to turn the fuel off and chance a float sticking and possibly hydro locking a motor, don't have to have a pingel, and much easier to purge w/one fuel supply line.

 

To get to the question, I am on the fence. I ran 39PWK's and for some reason had to run my PJ wide open w/.120 mains in the heat of the summer. I went to 41.3 lectrons the very next year w/two PJ's and can almost barely open one and am fat in the middle of summer. Easier to adjust, but can't quite fine tune the low/mid ckt like I'd like. Most of my friends and my builder swear the 39 PWK's are the way to go.....I am still trying to decide which one I am going to run this summer.

I got a second set of pumpers im gonna set up for backups you can throw on again and try when the time comes damian

39 pwk gravity fed carbs with billet bowls get my vote.
