Do you know if with a pulsa jet if it normally is supposed to inject a squirt of neat fuel into the throttle during starting to get things going? Don't see the mechanism for doing this.
No mechanism other than the choke and the intake vacuum.
Do you know what ACR is mentioned in the previous reply?
Forgive me I forget sometimes that not all are familiar with the ACR term. It is an automatic compression release device. On newer engine is usually a spring loaded swing arm on the camshaft that lowers compression by bumping one of the valves near dead top center (TDC) compression stroke a split second at start up to make starting easier for manual pull and electric starters. On older engines such as your '69 it would be either a ramp or bump ground on the camshaft lobe journal usually for the exhaust valve. Once the engine is up to operating speed these are normally no longer effective.
What I was referring to was that L-heads (side valve) engines tend wear the valve train in such as way that the valve clearance close up making the bump decompression more pronounce. If the valve train has enough wear it can actually have zero clearance. I even seen a few where the exhaust valve clearance was in the negative range. Basically the valve just stays open too long (duration time). Great to make the engine free breathing but terrible for start-up compression because of the ACR.
The solution is a valve job to regain the needed clearances. During the process of the valve job you may find the valve faces need lapping and valve guides need replacing. It may even be worse depending the engine use. You just don't what you find until you actually start the valve job but the first step is to check the valve clearances. These are .005-.007" Intake and .007-.009" Exhaust for the 080000 series. During the valve job I tend to set to the higher clearance to extend the life of the valve job just as I set to the lower clearance on OHV as they wear right the opposite of L-heads.
