Default engine bearing question.

Ok. I am replacing bearings on 2 of my engines. The thing is, i don't want to take the carburator's off. They are seeled on there, and i don't want to risk losing another thermal sleeve. So is it ok to put the engines in the oven at 300 degrees with the carburator still in the case?

Or, should i take the boot and all the needles and o rings out? I really don't want to do that unless i have too. I really don't like making a thread for this, but i really nedd advice from some of the experts, and i need it quickly. Race day!!

I have run my speed at around 300 degrees for a 30 min main and the only thing that went were the bearings. I would def take the carb boot off. Too bad you weren't closer I have a bearing pulled that takes no heat. I would say you are ok but I am not 100% on that.

thanks. I went ahead and took everything out minus the mid range needle just to be safe.

Default Well

Drop the oven temp to 250 just to be on the safe side. If they won't come out then try 300....

Would you rather take a chance on having to buy
a new thermal sleeve or a new carb body and a new
thermal sleeve? As many engine bearings as you replace,
I think you should buy a good set of engine bearing tools.

Take the carb off. They cost too much to possibly ruin by heat. Sometimes you have to heat to 350-400 so the bearings fall out.
