I have a 44cc twin setting 3ft from me, a great little engine it is !!

drop that Delorto carb quick and get yourself a Wabro,, if your engine starts dropping a cylinder at lower RPMs it is to lean on the low end,, run no more Nitro than 3% and no more oil than 8%, only Castor is needed but I guess some synthetic could be used ??, run hot plugs because it's a high compression engine, compression ratio is 11 to 1,,

if the cooling fins on top of the heads are a good 1/2 inch taller than the glow plugs it is a Super, it should be close to the power of a DA 50, but that power comes in a different form, it comes from higher RPMs,,

I plain to prop my Twin at 7800/8000,,


call here for a carb, just tell Mr. Cline you want a Walbro for your 44cc twin,,
