Good Day,

I am having an issue that i need some assitance with, whoever can assist me, kudos to them. Ive posted here about my old rossi engine the MT12. The engine has never been rebult and has had at least 3 full galons of the same fuel put through it from 99 to 2007. after the car gets going for about 6 to 7 mins the engine works well, but after it begins to bog at full throttle, only sometimes tho. The engine runs hot 210 220 deg, which is how hot the engine has always ran. compression is still there with the engine but personally i figure the engine may be on its way out. What could result in the engine boging at full throttle on occasion? and what steps should i do to try and fix it? at this point the car has been taken apart totally, and is being rebult since i just finished my weekend of racing. Whatever you guys reccomend i will take to the bank and make the neccessary changes.

Thanks again

Cole.
