premix clogging fuel filters
 

at 5k rpm I start breaking up.
when I premix anybody have had this issue ?
I was running supertech tcw3 I recently got quick silver tcw3 synththiec blend to see If it does the same

Have been running Supertech TCW3 the past 5 yrs in my 100K mi 12A/80GS @ 8oz/tank with no issues...
What is your mixture ratio? How old are your plugs? When was the last fuel filter change?

Worth $10 to run a can of Seafoam thru a tank of gas (I do this twice a year),
or
maybe even do a pour down the carb as its running (sl-o-o-o-o-owly, you don't want to stall it out with this procedure). If your engine is really carbon'd up this can be a great clean-out procedure. But you will not want to be doing it where you will annoy the neighbors! Smoke is Epic.

I think you have something else going on, but we need more info to assist...

Did you remove the filter to see if it was clogged? Why do you think its clogged? Breaking up at 5K could be many things. More history needed.

I will never again try seafoam I did it and it had so much rust coming out my tank I was clogging fuel filter every 20 miles. I think its my fuel tank that has crud inside that's why im breaking up imma have to drop the tank I already got the por 15 gas tank sealer kit . I recently purchased a gallon of quicksilver synthic blend premix thinking it might be the cheap supertech but I was reading a lot of people using it with no issues. my mechanic told me I should try to nylon filter if that don't work I guess amma drop the tank

Thats just seafoam doing its job. You need to refurb that tank if that much gunk is coming out. A better filter will just clog sooner.
