[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->I don't know the "proper" jet size but if its all stock with a stock cam... then you probably already have the proper jet size.
A carb kit and a simple "boil-out" with a carb cleaner will work wonders...
When you reassemble the carb add a bit of gas to the bowl before installing the horn, then install the air/fuel (A/F)mixture screw 'til it stops (NOT TIGHT!!!), then back it off a turn and a half.
Remount carb and start engine. Allow it to warm up to operating temp and insure the choke butterfly is completely open. Adjust as necessary using the three screws on the side of the pot so its fully open when engine is warm.
Get it to idle around 750 rpm and adjust the A/F for MAXIMUM RPM, then readjust idle screw back down to 750 again, adjust the A/F again for MAX RPM and LEANEST (Screwed in the most) possible, readjust idle to 750.
That oughta do it.
Any questions... reply direct.
Tony
p.s. on 79's... the carb A/F and idle screws are accessed from the rear trunk with a long scredriver by removing two plastic plugs... I think your's is the same.
