Hi All,

I have an unmarked Webra .20 or .28. I would like to find out which one it is. Aaron, and I, have ran the .28 in the past but I do not know which engine this is. I do not have an inside mic.

Thanks
Bill

Bill, a dial caliper will be sufficiently accurate. The bore of a .28 is .728" You could probably measure with a steel rule and be close enough since a .20 will be quite a bit smaller.

Thanks, Bill. So the .28 is .003 larger than .725 which is basically 5/8ths" IIRC. Sounds good.

Thanks, again!
Bill

No, .625" is 5/8"! So, .725" is 5/8" + .100". Just a bit over 23/32", actually.

Mea culpa, Brother Steve, not sure of what I was thinking! .725 is just shy of 3/4" (.750)!

Thanks!
