HPI 4.6 v2 Engine Starter Spring and Pin

[Dazn]

Hi All,

Really stumped.

Got a HPI Savage F4.6 v2 and manual in front of me so absolutely sure this is the engine.

Am trying to reassemble the backplate with part number 1433.

How on earth does the starter spring and pin sit when you install the backplate.

The spring seems to long and the pin won’t stay without flying off.

The spring goes into the hole followed by the pin in the part of the crankshaft that the conrod rotates around.
The face of the starting shaft then butts up against the pin when assembled.
Has your spring been stretched?

Yep did that - side by side the spring is longer than the pin - when the spring is in the hole it is sticking out loads

The pin sticking out is by design.
The little groove in the flat end of the starter shaft is how the pin engages with it to turn the crankshaft to start the engine.
The spring will compress when you put the backplate on.
Once the backplate is in place, you should be able to turn the engine over by spinning the shaft one direction and not turn over when you spin the shaft the opposite direction.
