Low-speed throttle control feels precise on technical trails, and the engine pulls cleanly into the midrange. Restarting after a brief stop is quick, without excessive choking or repeated kicks.

Alfredo Rosario
The engine settles into a calm idle shortly after using the choke. Roll-on response at cruising speed is crisp, with no flat spot when opening the throttle.
E
Eddie Johnson
Cold starts require much less effort, and the idle settles quickly without repeated throttle input. Power delivery feels even from cruising speed through stronger acceleration.
C
Calliope Marlowe
The float level stayed consistent, and there was no fuel seepage after the first heat cycle. The engine recovers quickly after a sudden throttle input without bogging down.

The manual choke gives me precise control during cold starts, and the engine responds cleanly once warmed up. Fuel delivery remains steady even under heavier throttle.

Compression feels even again, and the engine pulls strongly during steep climbs. The gaskets remain dry after several heat cycles, with no visible oil smoke from the exhaust.
The mounting holes aligned with the factory points, and the plate sits firmly beneath the radiator support. It clears the surrounding panels properly, with no vibration or rattling on uneven roads.
After the overhaul, drive and reverse engage promptly without the previous delay. The seals fit their channels correctly, and shift pressure remains consistent through every gear.
Commanded and actual fuel pressure now track closely during acceleration. Idle remains steady, and the engine pulls under load without surging or sudden power loss.
