when i have my engine running at high revs it lasts only around 1 second before it decreases in revs but still holding full throttle on, this is confusing me??

im just wondering if too much fuels getting in at full throttle so it doesnt ignite and revs decrease??

well thats wat i thought anyway,

any help would be greatly appreciated

It could actualy be to lean. Is ther a decent amount of smoke trailing the exaust when you gun it? If not you you should start to richen HSN a little at a time until you get desired performance and temps. Also check you other needle setting.

well there is always plenty of smoke coming from the exhust and the engine temp is fine
so thats why i was guessing it was more on the richer side

but i just want to make sure, incase i screw up bigtime

also it idles very well and runs very well its only when it reaches its higest rpm that it decreases

Then reverse the process and picture the face of a clock around the needle and start leaning it out one hour at a time until you get desired performance and temps.

cheers man,
thats wat i was thinking of doing in the first place but becasue im a begginer to all of this i just wanted to make sure!
