May have sold the McCauley for $1,500 including shipping. It’s iffy at this point. Respondent is vague about a lot of information. Will repost if this becomes problematical.
Restriction on the McCauley is if you hold RPM at a “continuous” 1850-2335 RPM. Otherwise, mine didn’t have a problem.
Sensenich has a restriction too “if” you have a hollow crank on the 0-360. No restriction if a solid crank.
