1979 skier 700 spark advance issue

[jmb1956]

I have owned a 1979 700 skier for 15 years,a few years ago the spark advance quit working properly. I am wondering if a part between the throttle linkage to the mechanical spark advance fell off and is missing . If I manually rotate the distributor (power time) I achieve great engine performance and power! Otherwise, I have no power. Is there an exploded view of this linkage somewhere I could look at?

Hello, recently experienced exact same problem exact same motor...found adjusting screw and black plastic eyelet that attaches to timing arm, they were laying deeper down in motor case(still able to retrieve by hand)...however, plastic connection at distibutor end was indeed cracked and broken in two pieces...we are fabricating a replacement part and are available by my yahoo email or by pm on iboats if you would like to compare notes, such as if you or I are able to locate repl part, or if you would like us to fab one for you, also willing to compare notes regarding correct setup/timing once replaced...Thanks RL Taylor heritagesvcco@yahoo.com
