tue or false, you'll lean sieze a single carb 62t at WOT

Yeah yeah same to ya kiwi fruit!

What ever, i cant be bothered arguring with you and getting involved with childish name calling

hell, thats actually my GOAL...
to make as much power as I can, at the brink of blowing to hell, on the cheapest gas i can run.

ive been running 87 octane since Thursday, and haven't melted my junk yet, I even leaned the top screw a bit while experimenting....

i went way longer than 40 seconds WOT a few times too, the pisser burnt the shiat out of my leg...

also its easy to build an engine thats good for just 1 second brapps much harder to make an engine that a customer can hold flat out for 40 secs +
like a race engine

up the compression some more and crank some more timing into it
you will achieve your goal

the poll question should read:

Putting a single carb on a 62t case will sieze a motor on WOT runs.


Can't edit the poll question.

not if the carb is tuned properly

i have been using a single 48mm/62t for a few years now with no problems

I ran a single 44 on a RIVA manifold for a 2 seasons or so no problems, as well as a BCW with single 48 for a season (cylinder ended up cracking)

Yeah but when that you bueat engine melts down due to to much compression , to much timing or badly mismatched combinations of a hole lot of things then its easy to say you held it wot with your single carb

also its easy to build an engine thats good for just 1 second brapps much harder to make an engine that a customer can hold flat out for 40 secs +
like a race engine

very true!

Lmfao ! :haha:

 

[Mouthfulloflake]

yep, need smaller domes...

got the timing, static, and MSD enhancer.

boat sounds like a chainsaw when the pump is unloaded and im on the trigger...

I like it.

when it blows up, ill build something bigger/better

up the compression some more and crank some more timing into it
you will achieve your goal

See if it will run on diesel. :cool2:

Maybe even a shot of kero in the tank

I have found that the single carb lean-out has most to do with venturi size and manifold design. Small carbs seem to always work great but big ones can be problematic. All we have for manifolds are Kawi 650s and the ATP, which is nothing special. If you get a big single be very careful until you are sure its no going lean at WOT. The easiest way to tell is by jeting very rich and see if it cleans up after several seconds at WOT. If it goes from too rich to normal it will go from normal to lean.

Thats great advice
a large carb on a small intake manifold will result in the intake manifold being the restriction and you wil not get a good pull on the jets
I can see this causing a lean seziure and this it why the higher flowing atp would be better than the 650 style
