Super Mta

[SMTA]

I have a Super Mta, and I see alot of talk about venturi"s. My carb is stock so what size is in my tractor? Also I have increased cubic inchs to 281 with high compression pistons and an LP gas head with bigger values. I have electronic ignt. and have drilled out the jets in the carb. Do I need a bigger venturi?

Thanks

Can't tell from here you'll have to take it out and measure it . It may have numbers on the outside of the venturi (after you take it out) like 25 or 27 and these will be dimensions in 32s and that will be the size.

You might wanna try finding a number 29 venturi. Unless its already got a 29 I got mine out of a 706 gasser i do not know what else they come in. I got a firecrater kit in my super m and i drilled out the jets in my carb and i went from a 27 to a 29 in my carb and it works great
